NELSON CROSS, OF NEW YORK, N. Y.

CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 240,305, dated April 19, 1881.

Application filed February 17, 1881. (No model.)

To all whom it may concern:

Be it known that I, NELSON GROSS, of the city, county, and State of New York, have invented a new and useful Improvement in Car- Axle Lubricators, of which the following is a specification.

My invention consists in forming the vertical spring frame-work of a lubricatin g-machine, including the arbor upon which the mounted cylinder revolves, of one continuous piece of wire, thus obviating the necessity of a separate axle and axle-bearings, as hitherto con-, structed and employed in similar devices.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a drawing of the above mentioned spring-frame, which may be of any required configuration. Preferably, however, the bottom coil or section should be made to conform to the shape of the oil-box cavity, to prevent its turning out of place. It will be ob served that the upper part of the frame is formed so as to present two parallel bars, which are extended beyond the body of the frame at one side, in order to form a support for a pad or wiper at the shoulder of the axle, as shown in Fig. 2. Fig. 2 is a drawing of the said frame, with the revolving spool or cylinder and pads or wipers thereto attached, as the machine appears when ready for use.

Referring to Fig. 1, A is the frame entire, b is thearbor or axle on which the cylinder revolves, and c c are the upper parallel bars of the frame.

Referring to Fig. 2, D is the revolving cylinder. e e are the lappers, which are attached to its depressed center portion and convey the oil to the axle. f f are the side pads or wipers attached to the parallel bars 0 c, and g is the shoulder pad or wiper attached to the projecting ends of the bars 0 c. The axle-line of the cylinder D is bored to receive the arbor b. It should be hushed at either end, leaving the bore between the axle-bearings large enough to prevent contact with the axle by the swelling of the wood. The lappers c 6 should, of course, be flexible, and varied in kind and capacity to suit the consistency of the lubricant employed.

When the lubricator is properly adjusted in the oil-box of a car-axle, the cylinder D is brought in frictional contact with the axle, and thus made to revoly e with it, while the wipers ff act upon the axle in such manner as to prevent the scattering and waste of oil. The wiper 9 serves a like purpose atthe shoulder of the axle journal-piece.

I am aware that nearly all the elements of my invention have been employed for the purpose above indicated but I am not aware that the entire frame and arbor of a lubricatorsimilarly constructed have been made of one continuous piece of wire, from which great advantage as well as economy of construction are attained, inasmuch as no separate journal-box is required, and it is rendered quite impossible for the axis to shift from a true direction. Another advantage is gained in the construction and adaptation of the cylinder in connection with the fixed arbor, in that there is no projecting journal or axle end to hinder the free action of the frame in the oil-box, to insure which it should be inclined inwardly from its base upward, allowing for the thickness of the side pads.

I claim as my invention- The frameAand arbor b, constructed of one continuous piece of wire, substantially as herein described, and for the object indicated.

NELSON GROSS.
